7 Application filed June 24, 1908. Serial No. 440,197.

To all whom it may concern:

Be it known that I, JOHN BERLIN Fnosr, a Citizen of the United States,residing at Jefferson, in the county of Coos and State of New Hampshire,have invented a new and useful Improvement in Wheels, of which thefollowing is a specification.

This invention relates to spring wheels and consists in the mattershereinafter described and referred to in the appended claims.

Figure 1 is a side elevation of my wheel a side plate being removed. Fig. 2 is a vertical section taken diametrically through the wheel. Fig.3 is a detail perspective view of the spindle portion of the hub. Fig. 4is a detail view partly in section showing one of the springs. Fig. 5 isa detail perspective view of the outer or wheel portion of the hub.

In these drawings 1 represents the ordinary spindle and 2 a Wheel, bothof which may be of any of the ordinary forms of construction. The hub ispractically formed in two separate sections, one section which I willcall the inner member being formed with a hollow body portion 3 throughwhich the spindle 1 passes and in which it is suitably ournaled. Thisbody portion has circumferentially formed about it a series of outwardlyprojecting ribs 4 arranged longitudinally with respect to the bodyportion, and these ribs are provided with sockets 5 both upon theirouter and side faces. The hub is also provided with sockets 6 placedbetween the ribs and preferably formed in pairs. The outer or Wheelportion of the hub consists of a band 7 formed of metal and bentinwardly or offset at certain points to form inwardly extending ribs 8,said ribs intermatching with the ribs 4 of the inner member 3. Upon thesides of the wheel portion are secured rings 9 connected by suitablebolts 10, said rings having inwardly extending lugs which fit in thegrooves formed by the bending inwardly of the metal band 8 to form theribs 9, the tenons of the wheel spokes also fitting in said grooves andbetween the lugs of' the rings 9. The inner member 3 being placed uponthe spindle, the outer portion 2 is assembled thereon and is supportedfrom said inner member 3 by a plurality of short springs 11. lVhilethese springs are similar in construction they are so arranged as tosupport and brace the construction in every direction. A portion ofthese springs are seated in the sockets 5 of the inner member 3 and bearupon the outer hub portion of the wheel formed by the band 7, and aportion of them are seated in the sockets 6 and bear against the ribs 8of the band 7.

It will be obvious that the springs 11 seated in the sockets 5 formed inthe sides of the ribs 4 will bear against the sides of the ribs 8 thesebeing circumferentially active springs, those seated in the outer endfaces of the ribs 4 will bear upon the inner face of the band 7 atpoints between the ribs 8, while those seated between the ribs 4 willbear upon the inner end faces of the ribs 8 the last two sets beingradially active springs. By this arrangement each set of springs, thesprings being preferably arranged as previously stated in pairs, isarranged substantially at right angles to the adjacent springs.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. A vehicle wheel comprising a rim and a hub, said hub including anouter member to which the spokes are attached, and an inner memberengaging the axle, said outer member having inwardly projecting springsupports, the face of the inner member having radial arms extendingtherefrom, a set of radially active springs interposed between the faceof said inner member and the inwardly projecting spring supports of theouter member of the hub, a second set of radially active springsinterposed between the outer ends of said radial arms, and the outermember of the hub, and circumferentially active springs located at aradial distance intermediate the sets of radially active springs, saidcircumferentially active springs being substantially circumferentiallyalined and each of said circumferentially active springs engaging at oneend one of the radial arms and at the other end engaging one of theinwardly projecting spring supports.

2. A vehicle wheel having a hub, including an outer member to which thespokes are attached, and an inner member engaging the axle, said outermember having inwardly projecting ribs and the inner member havingoutwardly projecting ribs extending into the spaces between the inwardlyprojecting ribs on the outer member, radially active springs eachbearing at one end on the face of the inner member between the outwardlyprojecting ribs thereon and at its other end bearing on the inner faceof the inwardly projecting rib on the outer member, other radiallyactive springs each bearing at one end on the outer face of one of theoutwardly projecting ribs on the inner member, and at its other end onthe inner face of the outer member between the nwardly pro ecting ribsthereon, and 01rcumferentially active springs, substantiallycircumferentially alined located at a radial distance intermediate thesets of radially active springs, each circumferentially active springengaging at one end the side face of one of the outwardly projectingribs on the inner member, and at its other end engaging the side of oneof the inwardly projecting ribs 011 the outer member.
